【問題】如何使彈出的消息框延遲1秒后自動消失？
void CRichedDlg::OnButtonTest() 
{
    SetTimer(1,1000,NULL);
    MessageBox("Test","Test1");
 }

void CRichedDlg::OnTimer(UINT nIDEvent) 
{
    if(nIDEvent == 1)
    {
        HWND hwnd = ::FindWindow(NULL,"Test1");
        if(hwnd)
            ::SendMessage(hwnd,WM_CLOSE,NULL,NULL);
        KillTimer(1);
    }
    CDialog::OnTimer(nIDEvent);
}
